Lesson objective: Compare two two-digit numbers using a < or > symbol.

This lesson helps to build fluency with two-digit comparisons. The game Ocean World is used here because it supports place value connections. This work develops students' understanding that two two-digit numbers can be compared using the < or > symbol.

Students engage in Mathematical Practice #2 (reason abstractly and quantitatively) as they critically think about the relationship between quantities, using flexible thinking of mathematical symbols.
